#1 no ideas on that one
#2 Looks like a A/C compressor clutch connector
#3 I know the black/wht is for something on the TB, can`t remember if its the idle air control or the TPS sensor. The grey connector looks like IAT.
#4 The only connector that I can remember thats red is the one that connects to the power steering solenoid, but I thought that was only on trucks.
#5 looks like the EVAP purge solenoid connector.
The easiest way to verify them is with an ohmmeter, just check between the connector and the pins that they go to on the PCM
